Question

The synapsis occurs between

• A. male gamete and female gamete
• B. mRNA and ribosomes
• C. spindle fiber and centromere
• D. two homologous chromosomes

Answer 1

Answer:

D. two homologous chromosomes

• The synopsis is a step in meiosis that occurs during prophase I, where two homologous chromosomes come together to form a bivalent or tetrad.

• The chromosomes align side by side and are held together by the synaptonemal complex, which facilitates crossing over an exchange of genetic material between non-sister chromatids.

• This process of genetic recombination is integral to generating new combinations of alleles, ultimately contributing to genetic diversity.
